Abstract

We characterize optimal strategies in a simple herding model where observations have a small cost. We assume that there are two states and two possible signals that each agent may get. The prior distribution is biased towards adopting behavior. That is, ex-ante, adopting gives a higher expected utility than not adopting. Contrary to Kultti & Miettinen (2005) herding does not arise deterministically in this model when the cost of observation is small.
